Formation of coal
Organic matter derived mostly from land plants accumulates in low-energy environment like a swamp
Oxidative decay uses up lots of oxygen, rendering the sediment pore waters devoid of oxygen anoxic
Gentle cooking and pressing (lithification) as a result of increasing burial depth remove the pore water and increase carbon content due to release of volatile components of the organic molecules
Low grade coal (lignite) cooked very little
High grade coal (anthracite) cooked a lot close to being a metamorphic rock
Lower grade coal tends to contain minerals such as pyrite, which formed under the reducing (low-oxygen) conditions
